LSModel (LocalSolver 6.5 API)

java.lang.Object
- localsolver.LSModel

```
public class LSModel
extends java.lang.Object
```
Mathematical optimization model. A model is composed of expressions (some of which are decisions), organized as a tree. Then, some expressions of the model can be constrained or optimized. Once your optimization model is created and closed, the solver can be launched to resolve it. Note that you cannot modify a model which has been closed: you must reopen-it (with open()) or instantiate another LocalSolver environment to optimize another model.

- Method Detail
  - getLocalSolver
```
public LocalSolver getLocalSolver()
```
    Returns the LocalSolver object associated to this model.
    
    Returns:
    LocalSolver object.
  - createConstant
```
public LSExpression createConstant(long value)
```
    Creates a constant expression representing the given value. Only allowed in state LSState.Modeling. Note that if a constant has been already created with the same value, this method can return the same expression, but it is not guaranteed. The exact behavior is implementation defined.
    
    Parameters:
    value - Value of the constant.
    
    Returns:
    Created constant expression.
  - createConstant
```
public LSExpression createConstant(double value)
```
    Creates a constant expression representing the given value. Only allowed in state LSState.Modeling. Note that if a constant has been already created with the same value, this method can return the same expression, but it is not guaranteed. The exact behavior is implementation defined.
    
    Parameters:
    value - Value of the constant.
    
    Returns:
    Created constant expression.
  - createNativeFunction
```
public LSExpression createNativeFunction(LSNativeFunction func)
```
    Creates a native function. Once you instanciated it, you have to pass arguments to your function and call it. For that, you have to create expressions of type LSOperator.Call. The first operand must be your native function. The other operands must be LSExpressions. Their value will be made accessible to your native function through the native context.
    Note 1: Most of the time your native function will be called when the solver is in state LSState.Running. Do not attempt to call any method of the solver (to retrieve statistics, values of LSExpressions or whatever) in that state or an exception will be thrown. The only accessible function is LocalSolver.stop().
    
    Note 2: Your functions must be thread-safe. According to the "nbThreads" parameter, LocalSolver can be multi-threaded. In that case, your native functions must be thread safe. If you cannot guarantee the thread-safety of your code, we strongly recommend you to limit the search of LocalSolver to one thread with LSParam.setNbThreads(int).
    
    Parameters:
    func - Native function to call.
    
    Returns:
    The expression associated to the function.

    Returns:

  - addConstraint
```
public void addConstraint(LSExpression expr)
```
    Adds the given expression to the list of constraints. It means that the value of this expression must be constrained to be equal to 1 in any solution found by the solver. Hence, only boolean expressions (that is, expressions whose value is boolean) can be constrained. Only allowed in state LSState.Modeling. If the expression is already a constraint, this method does nothing and returns immediately. Try to avoid hard constraints as much as possible, because LocalSolver (and more generally local search) is not suited for solving hardly constrained problems. In particular, banish constraints that are not surely satisfied in practice. Ideally, only combinatorial constraints (which induce the combinatorial structure of your problem) have to be set. All the other constraints can be relaxed as primary objectives in order to be "softly" satisfied (goal programming). For instance, constraint a <= b can be transformed into minimize max(b-a, 0).
    
    Parameters:
    expr - Expression.
  - constraint
```
public void constraint(LSExpression expr)
```
    Shortcut for addConstraint(expr).
    
    Parameters:

    See Also:
    addConstraint(localsolver.LSExpression)
  - removeConstraint
```
public void removeConstraint(LSExpression expr)
```
    Removes the given expression from the list of constraints. If the expression was not constrained, this method does nothing and returns immediately. Only allowed in state LSState.Modeling.
    
    Parameters:
    expr - Expression.
    Since:
    
    5.0
  - removeConstraint
```
public void removeConstraint(int constraintIndex)
```
    Removes the constraint at the given position in the list of constraints. Only allowed in state LSState.Modeling.
    
    Parameters:
    constraintIndex - position of the constraint to remove.
    Since:
    
    5.0
  - getNbConstraints

  - addObjective
```
public void addObjective(LSExpression expr,
                LSObjectiveDirection direction)
```
    Adds the given expression to the list of objectives to optimize. A same expression can be added more than once. Only allowed in state LSState.Modeling. Note that the objectives will be optimized in the order in which they have been added to the model. It is useful for lexicographic multiobjective optimization, and more particularly for goal programming.
    
    Parameters:
    expr - Expression.
    direction - Optimization direction of this objective.
  - minimize
```
public void minimize(LSExpression expr)
```

```
    Shortcut for addObjective(expr, OD_Maximize).
    
    Parameters:

  - removeObjective
```
public void removeObjective(int objectiveIndex)
```
    Removes the objective at the given position in the list of objectives. Note that the objectives created after the removed one have their index decreased by 1. Phases are not modified when an objective is removed. It is the user's responsibility to change the objective index of each phase to keep it coherent (with LSPhase.setOptimizedObjective(int)), or to disable it (with LSPhase.setEnabled(boolean)). Only allowed in state LSState.Modeling.
    
    Parameters:
    objectiveIndex - position of the objective to remove.

    Objective direction.
  - getNbOperands
```
public int getNbOperands()
```
    Gets the number of operands in the model. This corresponds to the number of operands for all expressions declared in the model. It is an analog of the number of non zeros in matrix model encountered in mathematical programming: it gives an hint about the size and the density of your model.
    
    Returns:
    Number of operands.
  - close
```
public void close()
```
    Closes the model. Only allowed in state LSState.Modeling. Once the model is closed, no expression, constraints or objectives can be added. The model must be closed before starting its resolution.
  - open
```
public void open()
```
    Opens or reopens the model. When this method is called, the solver is placed in state LSState.Modeling. Only allowed in state LSState.Stopped.

    Returns true if the model is closed, false otherwise.
    
    Returns:
